User Commands (c) c99(1)

If -Wwarn=w is speciﬁed, then -Wnowarn must also be speciﬁed or the -Wwarn=w

ﬂag is ignored. If -Wnowarn=w is speciﬁed, then -Wwarn need not be speciﬁed.

If white space is present after the commas, the list of warning message numbers should

be enclosed in quotation marks.

-Wwarn is the default speciﬁcation for this ﬂag. -Ww overrides the -W[no]warn ﬂag.

-Wx Strips part of the symbol table from the output object ﬁle but keeps information neces-

sary for the object ﬁle to be used as input to a linker utility again. This ﬂag is typically

used with -Wr.

Multiple instances of the -D, -I, and -U ﬂags and of the -l operands can be speciﬁed.

The position of -l library operands within a list of ﬂags affects the order in which the libraries are

searched.

The order of specifying the -I and -L ﬂags is signiﬁcant.

Quotation marks around string values in ﬂags are optional but recommended to avoid errors

caused by shell substitutions or deletions.

Refer to the C/C++ Programmer’s Guide for details.

DESCRIPTION

c99 is a driver program for the native C and C++ language compilation system. The c99 utility

compiles C and C++ programs using the native TNS/E compilers. Source ﬁles must comply with

the C99 (ISO/IEC 9899:1999) standard, but are permitted to use HP extensions if you specify the

-Wextensions ﬂag. For source ﬁles that comply with the C89 standard or for programs that

require the compiler to process C source ﬁles traditional Kernighan and Ritchie C or Common C

rules, instead of according to ISO/ANSI Standard C, use the c89 utility with the -Wkr ﬂag.

This reference page describes using c99 in the OSS environment.

c99 performs simple validation of the ﬂags and operands from the arguments on its command

line and, depending on those arguments, invokes components of the language compilation sys-

tem. c99 does not verify the existence of ﬁles it passes to compilation system components. It

does verify that the operand sufﬁx identiﬁes a valid operand to pass to compilation system com-

ponents. c99 and the components it runs issue messages to the standard error ﬁle.

c99 performs the following steps:

1. If the corresponding -W ﬂag is speciﬁed, invokes the SQL/MX preprocessor to process

any embedded SQL statements in C or C++ source ﬁles, creating C only, C++ only, or

module deﬁnition ﬁles as appropriate.

2. Compiles any speciﬁed C and C++ source ﬁles or source ﬁles produced by Step 1 into

object ﬁles.

3. If the -Wmxcmp ﬂag is speciﬁed, invokes the NonStop SQL/MX compiler to process

ﬁles created by Step 1 or speciﬁed as module deﬁnition ﬁles in the command.

4. Links the object ﬁles together with any libraries speciﬁed on the command line. (This

occurs if no ﬂags that prevent linking are speciﬁed and the source ﬁles are compiled

without errors.)

5. Writes an executable object ﬁle or library to the ﬁle speciﬁed by a -o ﬂag (if present) or

to the ﬁle a.out.
